Title: Improvements in and relating to painting in colours
IPC: B05D1/32
Filed: 1928-10-10
Abstract: 323,565. Changeable Sign Co., Ltd., Emmerson, E., and Shurly, E. Oct. 10, 1928. Stencilling.-Relates to the printing in colours of designs, lettering, &c., for use in advertising &c. The material to be coloured is first covered with a sheet of metal foil &c., which is secured by means of adhesive, and the design or lettering is cut therein. The portions intended to be coloured first are then removed, together with adhesive, so that the metal foil forms a stencil. and colour is applied to the exposed portions of the material. The coloured portion is covered with a soluble masking substance, such as petroleum jelly or indiarubber solution, after which further portions of the design are exposed and coloured. The process is repeated until the whole design is coloured, when the soluble masking substance is removed. An embossed effect may be produced by applying several superposed coats of colour to one or more portions of the design.

IPC: F01L7/04
Filed: 1920-10-16
Abstract: 171,868. Paterson, T. W. Oct. 16,1920. Valves; valve-gear.-In an engine in which a rotary sleeve valve 1 is given a reciprocating motion such that its port is masked by the cylinder head during the greater portion of the compression and explosion strokes in order to prevent unbalanced side thrusts between the valve and cylinder walls, the longitudinal motion is imparted to the sleeve by a fixed cam groove 9 engaging rollers 12 on the sleeve, and the rotary motion by a toothed wheel 2 having projections 4 free to slide in grooves 3 on the sleeve. The sleeve mav be timed so as to move in the same direction as the piston. The invention is applicable to engines with a single sleeve between the piston and cylinder, and also to engines with two sleeves, the outer having a rotary motion, and the inner rotating at half the speed and receiving also the longitudinal motion.

Abstract: 427,426. Winding yarns. MOORE, B. J., Brynmede, Burbage, near Hinckley, Leicestershire. Oct. 26, 1933, No. 29724. [Class 120 (ii)] In a winding-machine in which the bobbin is rotated by an element frictionally driven from a driving wheel, the driven element is carried in a bracket or arm which is capable of a slight oscillating movement to move the driven element bodily away from the driving wheel and stop the machine when the yarn or thread passing to the bobbin becomes abnormally tensioned, the yarn &c. passing over a lever which turns a cam or equivalent member engaging, and thus moving, the bracket or arm. As shown, the bobbin is supported between a pair of centres 3, 14, the centre 3 being carried by the driven element or wheel 2 and with it being journalled in the bracket or arm 1 pivoted on a fixed shaft 16 and the wheel 2 being held in contact with the driving wheel 4 by a weight 10 at the end of a rod 26 fixed to the bracket. An arm 22 fixed to the shaft 16 has a cam 13 journalled therein with a nose on the cam adjacent the bracket 1 and the lever 7 projecting from the cam carries a guiding roller 8 over which the yarn &c. passes. The lever 7 is normally supported in a raised position by a spring 9 coiled around the journal of the cam 13 with one end secured thereto and the other end engaging one of a series of lugs 24 on a plate 25 projecting from the arm 22 ; when the tension in the yarn a becomes excessive the lever 7 is depressed and the cam is rotated so that the nose thereon engages a screw 11 in the bracket and forces the latter with the wheel 2 away from the wheel 4. The nose of the cam is undercut or shouldered so that after the bracket has moved the undercut engages the screw 11 to lock the bracket and hold the wheel 2 out of contact with the wheel 4. The screw 11 may be replaced by a roller or a springy plate adjustably mounted on the bracket. Reference has been directed by the Comptroller to Specifications 298,873 and 338,291, [both in Class 120 (ii)].
